The Mitch McConnell and Rand Paul show

The political sensibilities of Mitch McConnell and Rand Paul were on display this weekend, offering a textbook explanation of why the Senate Minority Leader is positioned to dodge a serious tea party challenge, and why Paul is poised to surpass his father on the national stage.

The public message from Kentucky’s two Republican U.S. Senators was crystal clear over the weekend: they’re on the same team.

U.S. Sens. Mitch McConnell and Rand Paul were liberal with the praise for each other at their first joint appearance on the 2013 Lincoln Day Dinner trail in Spencer County on Friday. It comes amid rumblings that some tea party groups want to see McConnell face a challenge from the right in the 2014 election.

Paul told Pure Politics on Friday that he “doesn’t see it happening.”

McConnell, the Republican U.S. Senate Leader, told the 280 Republicans at the dinner that Paul has “brought to the Senate what it really needed” and thanked Paul for running in 2010 to replace Jim Bunning in the Senate.

It hardly needs to be said that the two Republicans weren’t always so impressed with each other: McConnell opposed Paul’s bid to become GOP nominee in that race to replace Bunning.

But since then, by playing nice with each other both politicians have cultivated an unlikely relationship that reveals a lot about their political instincts – and the accommodations they’re willing to make to advance themselves.

McConnell, the godfather of the Kentucky GOP, instantly recognized the shifting terrain within the party and moved quickly after the 2010 primary to reach out to Paul and his libertarian and tea party supporters. Roughly two years after Paul’s upset Senate primary win, the Senate Minority Leader hired a top Paul family aide to run his 2014 re-election campaign.

At the moment, there’s no top tier primary challenger to McConnell on the horizon.

Paul has also shown a willingness to make strategic concessions. He endorsed Mitt Romney in June, a risky move that came at some cost among the supporters of his father, former Texas Congressman Ron Paul, who weren’t ready to embrace Romney.

The relationship with McConnell is also paying off: At the Kentucky dinner, the junior senator praised the Senate Minority Leader for using his clout to get him on the high-profile Foreign Relations Committee.

Paul’s approach is already showing dividends – at this early stage in his Senate career, he’s a far more viable GOP presidential contender than his father was in any of his campaigns.
